3 Claims. (Cl. 308-214) I a w invention relates to taper roller bearings it has a central tapered opening it larger than of the sell-contained type and has tor its prinsaid conical portion of said sleeve and substancipal object to provide means within the bearin flally parallel therewith, the thrust plate being itself to counteract the tendency of the cup hold on said sleeve ill by means of a ring i5 oi g outer bearing member tobecome separated from soft metal pressedin'to the conical space between 5 the rollers, which separation would reduce the the two members. A suitable closure plate i'l seradial load capacity of the bearing. 1 cured to the end of the housing holds the thrust The invention consists principally in mounting plate and bearing in position. v

at the small. end of the cone or inner bearing The outer peripheral portion it of the inner 0 member a thrust plate and inter-posing a serie face r said t r plate of conical s p with it t of tapered thrust rollers between said thrust I its apex A on the axis of the bearing, said conical plate and the adjacent end of the cup or. outer portion it constituting a racewayior said sec- .bearlng member. such thrust rollers being dis-- ondary series of taper bearing rollers 5 which are posed with their large ends outwardly so asto arranged with their apexes coincident with the have the effect of maintaining the clip or outer apex of said conical raceway it. The opposed 15 bearing member in proper running position on end face 0! the bearing 1? 9 18 P v w a the main rollers. The invention further consists conical ra y l for s rollers. with a hr in the roller bearing n in the rts nd comrib is for the large outer ends oi-said rollers and UNIT D STATE 0 described and claimed. of said .rollers.

A seal for the a .Pig. 3 is a si'milar'view of a slight modification, outer end or the bearin comprises a sleeve 25 The drawing illustrates an automobile. drive mounted on a re oo ed hou der p r n a h axle of the fixed hub or semi-floating typ inend or the bearing cup and having a curved D i'or terminating short of the end or the axle seca rabbeted; portion 28 in the outer periphery of tien. and a duplex taper roller bearing 13 interthe inner race or the th t p a e t posed between the enlargedend 3 of the housing In the modification shown in Fig. 3, the thrust and the axle. Said bearing includes a main set rib 8a iorthe rollers is in the cup tinstead of or rollers 4 mounted primarily to carry radial on the cone, and the thrust rib itaf r the sec- 5 load, that is,- disposed at a relatively low angle, ondary rollers is on the thrust plate I instead of and a secondary set of rollers t mounted after Q on the end or the cup 9, the construction being the fashion ot'a thrust bearing, that is, at a relaotherwise the same as Fig. 1. tively steep angle.
